PROBLEM TO BE SOLVED: To provide a compressor capable of efficiently restraining vibration at startup and a load to respective parts accompanied by the vibration even in a relatively large reciprocating compressor having large reactive force at startup.SOLUTION: A compressor includes a compressor body 1 compressing fluid, a motor 3 for driving the compressor body, a compressor pulley 2 rotated in accordance with driving of the compressor body, a motor pulley 4 rotated in accordance with driving of the motor, a belt 5 transmitting power of the motor pulley to the compressor pulley, a frame 7 in which the compressor body and the motor are arranged, and a vibration control member 6 for reducing vibration of the frame. A following expression is satisfied when a natural frequency in a case where the belt is used as a spring and the motor pulley is used as a weight is ω and a natural frequency in a case where the vibration control member is used as the spring and the frame and the ones arranged in the frame are used as weights is ωn. |
